Amazing, thank you so much, works perfectly. And I do mean perfectly! I have an old quad core (Q6600 @ 2.4 GHZ) with 4GB Ram and a GTX275. Not a bad setup but I expected the game to run much worse. Maybe because of the Il-2 Flaming Ciffs fiasco. With all details maxed at 1920x1200 (no AA) it runs smooth only dropping below 20 fps (but still above 15) near the ground at high speeds. So it's still perfectly playable.
As for the game itself, most realistic sim I've flown yet. Even with a Saitek CyborgX (very cheap stick) the plane is a joy to fly. This has to be the first ever sim I've managed to refuel in flight without soiling my pants. It's hard of course but the movement feedback you get with camera shake and HUD response is simply amazing. There might be imperfections down the road (cannot collide with trees..) but this is a 100% score sim.
The devs shouldn't even have bothered with copy protection, although it's quite harmless. Simmers will buy this just because ED, although alone on the PC hardcore sim market never rests on its laurels. And they deserve praise for that. This is a sim that will take months to learn, years to perfect, and the cost of the game is about 10% of the cost of a rudder+stick setup. I can't wait to find the box version (I never buy digital). The only problem is that now I have to spend 500+ euros on pedals and the Thrustmaster Warthog monster Hotas (not required but.. wtf..)
Oh, in case you were wondering, 5 years from now, when we'll all have virtual helmets, this sim will probably the first title I'll try.
